This book is an important contribution to the study of the Tibetan interpretations of Indian Madhyamaka thought. It consists of a new English translation of Nāgārjuna's Mūlamadhyamakakārikās from Tibetan, and the first translation of the commentary on that text by the twelfth‐century Tibetan scholar Tsöndrü. Until recently, modern scholarship on Madhyamaka had tended to focus on the interpretations of the Geluk sect and its founder, Tsongkhapa Lozang Drakpa (1357–1419). In the last two decades, this has begun to change; and this work is a welcome offering on a Tibetan scholar who predates the established interpretive approaches of the four Tibetan sects. Mabja's views set important precedents for the Tibetan understanding of Madhyamaka; for example, Mabja was an early proponent of the Indian commentator Candrakīrti. However, he also held views that differed from many later Tibetan Mādhyamikas, such as acceptance of the scriptures of the Third Turning of the Wheel of Dharma as consistent with the Madhyamaka view. The translation by the Dharmacakra Translation Committee is clear and readable while remaining true to the original Tibetan. Although one may wish that there were more than the four‐page translators' introduction to give the nonspecialist reader contextualizing information and analysis, this book is sure to be a valuable resource for the study of Tibetan Madhyamaka for those well versed in the literature of Madhyamaka.
